Maintaining your plotter Cleaning the cartridge nozzles (priming) MAINTENANCE 7 C A U T I O N Cleaning the cartridge nozzles (priming) To prime a cartridge is to clear clogged print nozzles manually, by using the green plunger at the left side of the plotter. Some of the circumstances in which it is useful to prime a cartridge are explained in chapter 9, "Troubleshooting", but essentially, if you suspect that the nozzles of a cartridge are clogged, try priming that cartridge, as explained here. 1 Leave the plotter switched on. If the plot in which you noticed the problem is still being printed, you will be able to check the result of the priming in the latter part of the same plot. So simply go to step 2 to interrupt the print. If you try to prime a cartridge while the plotter is switched off, you could damage the cartridges. 2 Open the cover. If necessary, wait for the cartridge carriage to move to the service station (the area on the left of the plotter).
